Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I am currently trying to calculate the beta function for scalar QCD theory (one loop for general su(n)).

I therefore need to calculate the Feynman rules in order to apply them to the one loop diagrams. Unfortunately I am getting very confused with what the Lagrangian for scalar QCD should be. If anyone knows of some clear examples of this Lagrangian and possibly the derivation of the corresponding Feynman rules and diagrams I would be very appreciated.

Many thanks
